Application filed May 9, 1923. Serial No. 637,709.

To all whom t may concern:

Be it known that I, ELIAS MoNnss, a citizen of the United States, residing. at 787 Crotona Park north, New Yori city, in the county of Bronx and State of New York, have invented new and useful vImprovements in Liquid Meters, of which the following is a specification.

The invention relates to liquid meters for varyingrates of flow of a liquid, and particularly toboiler-feed meters. The special object is to provide a very simple and reliable apparatus for recording on a chartthe rate of flow of feed-water to a boiler.

An examplilication of the invention comprises a horizontal board or the like suspended from a spring-balance; the feedwater flows out of a pipe, spo-ut or passage several feet above the board, falls on the board and produces an impact proportional to the quantity of water flowing per unit of time. rIhis impact acts upon or against the spring-balance, and a pen connected with the spring-balance or other part moves over a slowly rotating or traveling chart, tracing a curve which shows the rate of flowl for a given period. The water falls od the board into a tank, from which it is pumped into the boiler.

The accompanying drawing is a perspective view illustrating the invent-ion in a .somewhatschematic manner.

1 is a tank having an outflow pipe 2 leading from its bottom to the fed-water pump of the boiler.

3 is a horizontal board or impact member suspended above the bottom of the tank, as by means of cords, wires or rods 4, 5 and a frame 6, from a spring-balance 7 comprising a spring 8. To the indicator 9 cooperating with the scale 10 of the spring-balance is attached an arm 11, carrying a pen or tracer 12. The pen marks upon a chart 13 placed upon a cylinder 14, which is rotated slowly at a predetermined rate in a known manner. Obviously a circular chart may be used. 15- is the pipe from which the stream falls upon the board. In some cases the indicator and scale of the springbalance might be omitted, the essential being that the impact of the falling stream on the board be transmitted to and act against a spring. Manifestly the pen might be connected at another point in ,the mechanism,

and may be actuated either directly or indirectly. rlhe preference, however, is forthe very simple yet complete form of apparatus illustrated.

The particular advantage of an apparatus embodying the invention is its extreme simplicity and cheapness. Existing meters vfor the purpose are comparativelyexpensive, due largely to the fact that such meters have the pen operated by a loat in a tank.` The float rises and falls with the level of water in the tank, but this motion is not proportional to the flow, but to the two-fifth power of the How; hence an expensive cam arrangement is necessitated to transform the float motion into a motion directly proportional to the discharge.

Besides its advantages of simplicity, the present meter can be used. for both hot and cold water, it has almost no friction, and should be capable of operating for a long time without deterioration.

The level in the tank is kept below the board. For this purpose a float 16 connected with and controlling a valve 17 in the supply pipe is shown. As more or less water is withdrawn by the pump the discharo'e of water onto the board is regulated accor in' ly and the fluctuating rate of flow is recor ed on the chart.

It will be apparent that numerous other embodiments of the invention may be devised.

lV'hat I claim'as new is:

1. A meter of the kind described, having a yieldingly supported board, means for causing a stream of liquid to fallupon the board, and spring means for supporting said board, against which the impact of the falling stream upon the board acts.

2. A meter of the kind described, having a yieldingly supported board, means for causing a stream of liquid to fall upon the board, a supporting spring against which the force of the falling stream on the board acts, and a pen and connections whereby the pen is operated by and in accordance with the resulting movements of the board.

3. A meter of the kind described comprising a tank, a board, a spring-balance from which the board is suspended, means for causing a stream to fall upon the board, and a pen connected with the spring-balance.

4. A meter of the kind described, having a tank and means for withdrawing liquid a spring balance supporting the board,aganst by and in accordance withY t`h`e resulting and a valve and a connecton'between the Hoartvand the 4valere whereby-1th@ latter may therefrom;Z a suspended board, means for delivering a 4falling; stream yupen `wtnle boa-vd,
